Answer:
a) Function:Yes
b) Domain: 
c) Range: 
Step-by-step explanation:
The given graph passes vertical line test hence it is a function
The given function has x-intercepts at 
We can therefore write this function in factored form as 
There is a y-intercept at (0,-2)
The required function is
b) The domain refers to all values of x for which this function is defined.
The domain from the graph is because there are holes at the end of the graph.
c) The range is the value of y for which x is defined or the graph exists.
From the graph the range is
Answer:
the common ratio is 0.98.
Step-by-step explanation:
A fish population in a lake decreases by 2% each year. We are asked to find the common ratio.
The decrease of population of fish 2% annually means the population becomes next year 100% - 2% = 98%
Therefore, the common ratio would be 98%. Upon converting 98 percent to a decimal we will get,
98% = 
Therefore, the common ratio or decay factor is 0.98.
If we multiply the first equation by 2 we get
2x - 4y = 12
but the second equation is
2x - 4y = 10
2x - 4y can't have 2 different values so the are no solutions
Answer:
v=10.1
Step-by-step explanation:
v= 4.5 + at -------> equation 1
given
a=1.6
t=3.5
so we will plug in the value in equation 1
v = 4.5 + (1.6 x 3.5)
v = 4.5 + 5.6
v = 10.1
